Modular range has all positions covered

SKF Engineering Products has highlighted the breadth of its range of compact linear handling modules for use in all sorts of positioning applications.

SKF Engineering Products has highlighted the breadth of its range of compact linear handling modules for use in all sorts of positioning applications.

The linear axis components are supplied as basic guides and in powered versions, with a variety of bearing configurations, including roller guides and profile rail guides.

Increasing demand for automation and robotic handling solutions has similarly bolstered the need for modules from which systems can be designed and constructed.

The SKF linear handling modules enable any type of x-y-z gantries or linear motion arrangements to be built according to the specific needs of the application.

Special features include the use of a monobloc rail profile that removes the need for end caps and gives both rigidity and stability.

The carriages have a single point lubrication arrangement and installation flexibility is provided by the incorporation of a symmetrical bore for the motor housing, which enables the motor to be fitted from either side of the rail.

The belt driven units have pretensioned timing belts with easy access from the side of the unit.

This allows the belts to be changed without the need to dismantle the equipment.

On units using roller guides, the rollers have high preload to eliminate tilting moments that can give angular yaw errors at the load point.

The range starts with a simple linear table, which has no drive but is fitted with external roller guides with four or eight ball bearings, through to powered versions, with toothed belt drives, single and dual carriages and profile rail guides.

At the top end, the range includes high power linear actuators with linear motor or pneumatic cylinder, and mechanical types with ballscrew or trapezoidal screw motion.

In all, 33 variations are possible within the range, covering sizes from 62 x 34 to 240 x 85mm, loads up to 50kg, speeds up to 1.5m/s and positioning accuracy better than +/-0.15mm.
